I would just allocate array of the size of possible banks and grow nr_active_banks for active algorithms to keep the code simple because we are talking about insignificant amount of wasted space (might be even zero bytes given how kernel allocators works)>
Just beware that "possible banks" is tricky. While 2 is typical, getcapability will return a bitmap for each digest algorithm. This is
also currently 2, but will be 3 in the next TPM, is 4 in the SW TPM, and is potentially even higher. Also, account for a TPM that is malicious and can return a count as high as 0xffffffff. Range check count.
